AUTOMATIC CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 764,575, dated July 12,1904,

Application filed February 4., 1904. Serial No. 192,005. (No model.)

To all whom, it may concern;-

Be it known that I, ALBERT B. GARDELLA, a citizen of the United States,residing at N ewburg, in the county of (Juyahoga and State of Ohio, haveinvented new and useful Improvements in Automatic Car-Couplers, of whichthe following is a specification.

This invention relates particularly to automatic car-couplers of theJanney type; and its object is to provide an improved connection, incombination with a coupling-head, for the air-brake pipe.

In the accompanying drawings, wherein an embodiment of the invention isillustrated, Figure 1 is a plan view of a coupling-head embodyingtheinvention. Fig. 2 is an elevation of two heads coupled. Fig. 3 is across-sectional view on the line 3 3 of Fig. 1. Fig. 4c is a sectionalview on the line a 4 of Fig. 1. Fig. 5 is a view in elevation of theknuckle side of the head. Fig. 6 is .a perspective view of thelocking-pin removed. Fig. 7 is a View of the knuckle removed.

Referring particularly to the drawings, 6 indicates the draw-head of theJanney type, having a pivoted knuckle 7, which is held by a locking-pin8 in the general manner characteristic of this class of couplers. Thelocking-pin works up and down in the body of the draw-head in properposition to engage the tail of the knuckle and hold same when thecoupling is closed. The pin has a stout or large upper portion 8, anddepending from the rear side thereof is a thin guide portion 8, whichextends through a guide slot or opening formed in the bottom of thedraw-head.

At 9 is indicated a hooked and hinged latchpiece which is pivoted at 10in position'to hang down in front of the guide portion 8" and below thelower end of the main pin 8. The tail or rear arm of the knuckle has abeveled projection 7, which when the knuckle is closed strikes the latch9 and drops the pin. *hen the pin is lifted or set preparatory tocoupling, the lower end of the latch 9 rests upon the body of thedraw-head and supports the pin in raised or set position. When theknuckle comes around, the projection 7 strikes the latch, as referred toabove, and thereby withdraws the support for the pin, which thenimmediately drops in front of the rear arm of the knuckle. To uncouple,the pin is pulled up, at which action the hooked' latch 9 exercises aleverage against the projection 7, causing the knuckle to swing open.When the knuckle is closed, as in coupling, the latch is swung laterallyout of line with the pin, permitting the pin to drop in the manner abovedescribed. Now when the pin is forcibly lifted the hooked latch, bycontact of its back or upper edge with the upper wall of the cavity inwhich the tail of the knuckle swings, exercises a leverage on the tailof the knuckle, which has .the effect of swinging the knuckle outward oropen. 'The tail of the knuckle has also on the rear or back side thereofa lug 7 which when the knuckle is closed enters a recess 7 formed in thebody of the draw-head, and engages behind the front edge of said recess,so that the draft on the knuckle is not wholly on its pivot-pin andlocking-pin, but is sustained in part by the lug 7 engaging the body ofthe draw-head.

With respect to the pipe-coupling, it particularly embodies the idea ofputting the train-pipe line through the draw-head and having theangle-cock advantageously located in the coupling-head on the sideopposite to the locking pm. this is to shorten the flexible pipeconnection, make the pipe-coupling and angle-cock more accessible to thetrainmen, and avoid the necessity for separate fittings and casing forthe angle-cock.

In the drawings the train-pipe is shown entering the draw-head at 10,whence it is continued through a bore in the draw-head to the outlet 11on the under side of the coupling-head, at which place the flexiblehosecoupling 12 is attached. The angle-cock 13 is let or located in thebody of the couplinghead, across the pipe connection therein, which itcontrols in an obvious manner. Preferably the handle 1 1 of theangle-cock is so disposed that it will point straight ahead when thecock is open and will be stopped against a stop 15 when the cock isclosed.

By setting the train-pipe cock in the coupling-head a firm and solidcasing therefor is provided in very convenient position for ma- Thebenefit and effect of nipulation by the trainmen. The long lowhangingcoupling-pipes in common use are avoided, because the air-coupling ismade at practically the middle line of the car and very little will haveto be allowed for the variation in length incident to passing aroundcurves. The handle of the angle-cock being on top of the draw-head itcan be got at from either side very readily. It will not be necessary toget down under the coupling to get at the ends of the train-pipe, sincethe flexible trainpipe hose will be but a few inches in length-- onlylong enough to cross from one head to the other. The seat for the valveand also the pin.

causes the latch to swing down and be reset. The pin is always set whenthe knuckle is released.

What I claim as new, and desire to secure by Letters Patent, is

The combination with a coupling-head. of the Janney type, having apivoted knuckle on one side thereof, of a train-pipe which enters therear portion thereof and has an outlet at the front end adjacent thecoupling, and a controlling-cock for the pipe, in the couplinghead, saidoutlet and cock being in the side of the head opposite the knuckle.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ALBERT B. GARDELLA.
